Hi there, for my research project, I would like to control a fixed wing UAV from outside the flight stack. The example terminal Offboard mode is used for controlling vehicle movement and attitude, by setting position, velocity, acceleration, attitude, attitude rates or thrust/torque setpoints. However, my program is unstable somehow. I have been trying to use it via SITL with the iris model and have not been successful. The vehicle obeys a position, velocity or attitude setpoint provided over MAVLink. # Offboard Control Firmware Hello! I’m trying to flight using ‘mavsdk offboard example’ for python.

For what concerns QoS, as already suggested by @Kyuhyong_You, you can simply leave it as it is (the one in your post should work for all the PX4 topics). I am using a Jetson Nano on a Holybro drone and a Pixhawk 6C as FCU running on Ubuntu 20. Website. Hello Im very new , i try to folow the “MAVROS Offboard control example” But i not understand how to deal with the file “offb_node. launch I see The idea behind off-board control is to be able to control the PX4 flight stack using software running outside of the autopilot. You can see the list of /fmu/in/ topic (you can publish on them) and the list of /fmu/out/ (you can take values from them).
